Answer:
0, -8, 2
Step-by-step explanation:
Opposite of 0 is still 0.
Opposite of 8 = -8
Opposite of the opposite of 2: -2 is the opposite, then the opposite of opposite is -(-2) = 2
The price of televisions has dropped dramatically over the last three years. Three years ago a 32 inch television was $500. This year the tv was on sale for $199. What is the percent change?
A percentage is a way to describe a part of a whole. The percentage change in the price of the TV will be 60.2%.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is mentioned that the price of the tv 3 years ago was $500, while the current price of the tv is $199. Therefore, the percentage change in the price of the tv can be written as,
[tex]\rm Percentage\ change = \dfrac{\text{Initial value - Final value}}{Initial\ value} \times 100\%[/tex]
[tex]\rm Percentage\ change = \dfrac{\$500-\$199}{\$500} \times 100= 60.2\%[/tex]
Hence, the percentage change in the price of the TV will be 60.2%.

Choices- 333.50, 63.50, 153.50, 166.75
Answer:
153.50
Step-by-step explanation:
Sum of all interior angles of a triangle is 180°.
Option(1): 333.5 is much greater than 180(sum of all angles). 333.5 + 13.25 + angle P = 180, for all +ve values of angle P.
/_P = 180° - 13.25 - 333.5 , /_P is -ve from this which is impossible(for an angle in triangle)
This is incorrect.
Option(2): As it can observed, /_ R is much greater than 90°. It means, it should be greater than 63.50°.
This is incorrect.
Option(3): 153.50 is greater than 90°. Moreover, if /_ R is 153.5, let /_P be x, then,
=> 13.25 + 153.50 + x = 180°
=> x = 13.25. , which is +ve
So we can say /_P = 153.50
Option(4): if /_ R is 153.5, let /_P be x, then,
=> 13.25 + 166.75 + x = 180°
=> x = 0 , which is impossible(as we can see It's not 0)
Incorrect.

Find the solution of the system of equations.
4x – 8y = -44
2x + 4y = -6
Answer:
x= -7/2
y= 5/4
Step-by-step explanation:
x-2y=-11
x+2y = -6
then isolate x and set equal to each other
-2y - 6 = 2y -11
4y = 5
y = 5/4
then solve for x using y.
x+5/2 = -6
x = -7/2

Find sin 0, where 0 is the angle shown.
Give an exact value, not a decimal approximation.
Answer:
Answer: Sin0 = 8/8.5
Step-by-step explanation:
Step-by-step explanation: What we have is a right angled triangle, with two sides given and one angle which is the reference angle (unknown angle).
The Sine of the angle is calculated as
Sin0 = opposite/hypotenuse
We have the opposite side (facing the reference angle) as 8 units and the hypotenuse (facing the right angle unknown), which we shall label as X.
To calculate the hypotenuse, we shall apply the Pythagoras theorem which is,
X² = 3² + 8²
X² = 9 + 64
X² = 73
Adding the square root sign to both sides of the equation, we now have
X = √73
X = 8.5 (approximately)
Now that we have the hypotenuse as 8.5, the Sine of the angle can now be calculated as
Sin0 = opposite/hypotenuse
Sin0 = 8/8.5
A bicycle is on sale at a store for 15% off its original price. The original price, in dollars, of the bicycle is represented by the variable P .
Which of the following expressions represents the final sale price, in dollars, of the bicycle?
Select the two correct answers.
A p−0.85p
B p−0.15p
C 0.85p
D 0.15p
E p−0.15
Answer:
B
Step-by-step explanation:
Box A contains 10 pens that are either red or blue in colour. Box B contains 23 pens that are also either red or blue in colour. The number of blue pens in Box B is twice the number of blue pens in Box A while the number of red pens in Box B is thrice the number of red pens in Box A. Write a pair of linear equations using b as the number of blue pens in Box A and r as the number of red pens in Box A.
Answer:
b + r = 10 - - (1)
2r + 3b = 23 - - (2)
Step-by-step explanation:
Number of Blue pens in box A = b
Number of red pens in box A = r
BOX A :
Contains 10 pens that are either red or blue
b + r = 10
BOX B:
Contains 23 pens that are either red or blue ;
Red pens in box B = 2 tines the number of red pens in box A
Blue pens in box B = 3 times the number of blue pens in box A
2r + 3b = 23
The area of a square is greater than the area of the circle by 12 cm^2. Find the length of the side of a square if the area of the circle is 36 cm^2?
Answer:
Adding 12 to the circle area is equal to the square area.
Or
s2 = 12 + A
Where
s = side of square
A = area of circle
So
s2 = 12 + 36
s2 = 48
Solve this for s to get the side length
from the point p(-2,4) if PQ is drawn perpendicular to line 7x-24y+10=0,find the eqaution of the lin PQ . also determine the length of PQ
Answer:
7y+24x = -12
Step-by-step explanation:
Equation of line PQ in point slope form is expressed as;
y -y0 = m(x-x0)
m is the slope of {Q
(x0, y0) is the point on the line
Given the line 7x-24y+10=0
Get the slope
-24y = -7x -10
y = -7/-24 x - 10/-24
y = 7/24 x + 5/12
Slope = 7/24
Slope of the line PQ perpendicular to it = -24/7
Substitute m = -24/7 and (-2, 4) into the formula;
y - 4 = -24/7(x+2)
7(y-4) = -24(x+2)
7y - 28 = -24x-48
7y + 24x = -40 + 28
7y+24x = -12
This gives the equation of the line PQ
a rectangular canvas covers 225 square inches on a wall. If the canvas has a height of 18 inches then what is the base?
Answer:
12.5 Sq inches
Step-by-step explanation: 225 is the area and the formula for area is b*h (base times height) and from the problem, you can see that 18 inches is the height. In this case you would do 225/18 which gives you 12.5 sq inches.

Answer:
This is your answer ☺️☺️
Value of x is 19 cm.
What is area of trapezium?The area of a trapezium is defined as the number of unit squares that can fit into it . The area of a trapezium can be calculated using the lengths of two of its parallel sides and the distance (height) between them. The formula to calculate the area (A) of a trapezium using base and height is given as,
A = ½ (a + b) h where,
a and b = bases of trapezium, and,
h = height (the perpendicular distance between a and b)
Given
Area of trapezium = 48 [tex]cm^{2}[/tex]
Area of trapezium = [tex]\frac{(AB+DC).h}{2}[/tex]
48 = [tex]\frac{(AB+DC).h}{2}[/tex]
⇒ 48 = [tex]\frac{(5+x).(4)}{2}[/tex]
⇒ 96 = (5+x).4
⇒ 5 + x = [tex]\frac{96}{4}[/tex]
⇒ 5 + x = 24
⇒ x = 24 - 5
⇒ x = 19 cm
Hence, Value of x is 19 cm.
